IMO the humbling of Dems in the House could be a positive thing. Dems are out of touch with the working class, and increasingly, the middle class. They don't need to give ground when it comes to racism, sexism, homophobia, etc., but they do need to get in tune with the economic conditions and stresses facing so many. People get ugly when their basic needs aren't being met. Duplicitous and he was, Trump was speaking to them. Too often, Dems were speak down to them. That was Hillary's biggest sin. I think Biden understands this. Not sure about Harris though.
If you haven't listened to that Pod Save America episode where it's just a rambling 45 minute long interview of Biden, you should. That alone gave me some amount of faith in him that he understands the issues, and that's where you need to start. Everyone jumped on me/that episode about execution. But you know what, I don't give a shit about that right now - the foundation must start with understanding. The house...yeah...we need more AOC types in the house.
Let's hope Biden doesn't die. I think he will be a good president, and I'm happy to have supported him. I also think that in a high all voter turnout election that Dems were destined to lose some house seats. They vastly overperformed in 18. The House is so incredibly gerrymandered toward the GOP (by default and by design) that holding onto it is means that Dems have to have a good night. So I think it's less meaningful than most of the pundits are writing, even though I might agree that the "defund the police" sloganeering was unhelpful at best.
